Harkishan Singh, as per http://us.acer.com/ac/en/US/content/drivers an update to your computer's buggy and outdated BIOS is available (1.11). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-1.17 ** Tags removed: bios-outdated-1.17 ** Tags added: bios-outdated-1.11 ** Changed in: linux (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1528880 Title: freeze Status in linux package in Ubuntu: Incomplete Bug description: it freezes on acer aspire es1 311 ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-image-4.3.0-2-generic 4.3.0-2.11 [modified: boot/vmlinuz-4.3.0-2-generic] ProcVersionSignature: Ubuntu 4.3.0-2.11-generic 4.3.0 Uname: Linux 4.3.0-2-generic x86_64 ApportVersion: 2.19.3-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: kishan 1280 F.... pulseaudio CurrentDesktop: GNOME Date: Wed Dec 23 23:29:23 2015 HibernationDevice: RESUME=UUID=fc820305-0de5-4c71-9d6f-db63bfd59142 InstallationDate: Installed on 2015-12-21 (2 days ago) InstallationMedia: Ubuntu-GNOME 16.04 LTS "Xenial Xerus" - Alpha amd64 (20151213) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 04f2:b469 Chicony Electronics Co., Ltd Bus 001 Device 004: ID 04ca:300b Lite-On Technology Corp.
